By Inside GNSSThe future-oriented Navigation Technology Satellite-3 (NTS-3) spacecraft has taken one more step towards its in-space demonstration, scheduled for 2023. The satellite bus that will carry it has arrived at L3Harris Technologies of Palm Bay, Florida, delivered by Northrop Grumman Corporation.

A Department of Homeland (DHS)-chartered May 2021 report concludes that PNT threat and resilience concerns are not as dire as some have made them out to be, and that funds for backup could be spent elsewhere. Why this runs counter to other recent government reports is not clear, nor is the fallout from this divergence of Congressionally mandated views. The Department of Transportation has distanced itself a bit from this report by the RAND Corporation—and even its issuer, the DHS, seems to have done so.
BAE Systems selected Spirent Federal Systems to provide a controlled reception-pattern antenna (CRPA) test system to support M-Code military GPS technology development.

By Inside GNSSIridium Communications Inc. received a research and development contract worth up to $30 million from the United States Army to develop a payload to be hosted on small satellites that supports navigation systems, guidance and control for GPS and GPS-denied precision systems.
By Alan CameronNASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’ ability to understand and predict hurricanes. The total value of the contract is approximately $39 million. The CYGNSS Science Operations Center is located at the University of Michigan.
